Is there an example that uses time on x-axis that falls between two dates. For example shift production tracking between 6.00 PM to 6.00 AM, X-axis would be time and y-axis would be weight in tons.
Thanks |

You can modify starting time of the ScatterPoints.c chart in the ChartTabDemo example to produce a graph like the one you want. See the "// ***" lines. If you define the x-values to cross a day boundary, the auto-scale methods automatically take this into account
int numPoints = 20;
ChartCalendar []x1 = new ChartCalendar[numPoints];
double []y1 = new double[numPoints];
double []y2 = new double[numPoints];
int i;
double z;
ChartCalendar currentDate = new ChartCalendar();
// *** This is the only line that changes in the ScatterPoints example
// *** Set the starting time of 6:00:00 PM
ChartCalendar.SetTOD(currentDate,18,0,0);
// Define 20 points, equals 10 hours worth of data
for (i=0; i < numPoints; i++)
{
z = (double) i - 10.0;
x1[i] = (ChartCalendar) currentDate.Clone();
y2[i] =
.
.
.
currentDate.Add (ChartCalendar.MINUTE,30);
}
TimeSimpleDataset Dataset1 = new TimeSimpleDataset("First",x1,y1);
TimeSimpleDataset Dataset2 = new TimeSimpleDataset("Second",x1,y2);
TimeCoordinates pTransform1 = new TimeCoordinates(
ChartObj.TIME_SCALE, ChartObj.LINEAR_SCALE);
pTransform1.AutoScale(Dataset1, ChartObj.AUTOAXES_FAR,
ChartObj.AUTOAXES_FAR);
